Mark 15.5 rebreather

I still believe that the Mark 15 is the finest, most engineered, most
tested rebreather in the world, bar none. Mostly due to the
conversations on this list as to why the Mark 15 Series rigs are the
best rigs for everyone to use, and how by simply buying one, you begin
to look like a Greek God with chiselled features that make women swoon
at the sight of you and your manly rebreather, and also the
conversations about how extended use of Cis Lunars, or Inspirations can
cause gonad atrophy, loss of chest hair, sagging buttocks, and a
general repulsion of most members of the opposite sex. So I decided in
the general interest of those who wish to regain their youthful vigour
by investigating thoroughly these magic machines which bestow such
virility on their owners, to publish a list of comparisons of these
magnificent units. All those who read and memorize these pages will find
a new robustness in their demeanour which will bring a twinkle of
anticipatory elation to the eyes of all women they meet, and a knowing
smile from other valorous men who too have heard the Word, and seen
the Way. And those who actually own and dive a Mark 15 Series
Rebreather already know the satisfaction of Crushing their Enemies,
Seeing them Driven Before You, and Hearing the Lamentations of their
Women... Kevin Juergensen

Sidemount Sartori rebreather

Craig diving the Sartori rebreather in a sidemount configuration. As you can see from the photo there is a bit of tidying up of hoses required, but the unit worked well and shows some promise. Seen here in the original PSCR mode, but a reversible conversion to closed circuit is planned next.
